Product Specification
EU buyers source strip the same way they audit it: against the drawing, against the document, against the batch record. This copper-nickel composite strip is built for that standard — copper core for low electrical resistance, nickel cladding for weldability and corrosion protection, construction and dimensions per drawing. No grade designation applies; the construction is the specification. Every shipment carries EN 10204 3.1 material certificates, batch records and inspection documents, with export delivery in 7-15 days.
| Parameter | Value | Note |
|---|---|---|
| Construction | Copper core, nickel cladding | single or double-side, per drawing |
| Clad ratio | Per drawing | confirmed at order |
| Thickness | Per drawing | core + cladding layers |
| Width / length | Per drawing | strip form, per order |
| Tolerances | Per drawing | locked at order confirmation |
MOQ and exact tolerances are confirmed per drawing.
| Document | Content |
|---|---|
| EN 10204 3.1 MTC | Material test certificate with inspection results |
| Batch records | Construction, layers and dimensions per drawing |
| Inspection documents | Per-batch verification results |
Every coil can be traced from material selection to finished strip, so the audit trail matches the product.
| Layer | Role |
|---|---|
| Copper core | Low electrical resistance, current carrying |
| Nickel cladding | Corrosion resistance, weldable surface |
| Clad ratio | Confirmed per drawing |
Construction (single or double-side cladding), clad ratio, thickness, width, length and surface finish are all manufactured per drawing. Share the application and the drawing, and we confirm the strip specification before production.
Orders ship with export packaging suited to sea and air freight, shipping documents, and the material certificates EU buyers expect. Lead time is 7-15 days.
This composite carries no grade designation and is quoted per drawing, based on construction (single or double-side cladding), clad ratio, dimensions and quantity. No indicative price range is published for this product — request a quotation with your drawing for a firm price.
| Core material | Copper |
| Cladding material | Nickel |
| Cladding | Single or double-side, per drawing |
| Clad ratio | Per drawing |
| Composition record | Per-batch inspection per drawing |
Physical properties (density, electrical conductivity, tensile strength) depend on the core/clad ratio and layer thickness. Values are confirmed per drawing — no catalogue values are claimed for this composite.
| Form | Composite strip (Cu core, Ni cladding) |
| Grade | None (construction per drawing) |
| Size | Per drawing |
| Surface | Clean, oxide-free per drawing |
| Lead time | 7-15 days |
| Packaging | Export packaging per order |
| Dimensional tolerances | Per drawing |
| Nickel cladding family (where applicable) | ASTM B162 (Ni200/Ni201 strip); GB/T 2072-2020 (N4/N6 strip) |
| Material documentation | EN 10204 3.1 material test certificate |
| Composite verification | Per drawing, per-batch inspection |
Strip is packaged for export with edge and surface protection, suited to sea and air freight to the EU. Lead time: 7-15 days. Shipping documents and inspection records accompany every shipment.
Changzhou DLX Alloy Co., Ltd., established in 2002, operates a 12,000 m² factory rated at 1,200 tonnes per year. EU buyers audit the paper as carefully as the product: EN 10204 3.1 material certificates, batch records and inspection documentation. Every DLX shipment carries that file, with construction and dimensions confirmed against your drawing — so the composite strip arrives with its evidence attached.
A: EN 10204 3.1 material test certificates, batch records and inspection documents, alongside the shipping documents.
